DRYING FORM.

Application filedluly, 12, 1922. Serial No. 574,358.

.0;- all whom it may concern Be it known, that, I, Lnnor W. Hears, a citizen. of, the United States, residing at Springfield, county, of Delaware and. State of Pennsylvania have invented a new. and useful Improvementin. Drying Forms, of which the following is aifull, clear,,and exact description, reference being bad. to the accompanying drawings, whichform a, part of 10 thisspecificatien.

This invention relates, to an improvement in drying forms for wearing apparel, and more particularly relates to steam, heated metal drying forms, for drying hosiery, etc. am aware that hollow, steam heated metal, drying; forms for hosiery,,gloves, etc, whichare heated by steam supplied to the interior thereef, are, old inithe art, but. in all; suchforms known to me,- the forms. are fixedlyimounted on a suitable support so that itis quite difiicult. for the operator to inspect allaportions of the article onthe form.

Theobject of my. invention is to provide a-forn ofthis. character which can readily he turnedon itssupport so that the operator can readily inspect all portions of the article Without. substantially changing. hen position in. front of the. orm- The precise nature of my invention will be best. understood by reference to the accompanying; drawings, it bei remised, how.- eyer, thatohanges may be made-in the details of constructionwithout departing-from the spirit. and scope of my invention as defined-,in the appended. olanns.

Fi .-2 is.a similar view of aslightly modis tied. or

Fig.1?) is a. vertical section through the. connection between the form audits support.

Fig. 4 is a sectional plan view in the line 4.40.f. Fig. 3;.

Fig. 5 is a detail sectional view of a modified form of support.

Fig. 6 is a detail plan View of the clamp stO II; these drawings, the reference character a designates the drying form. which in this case is shaped for drying ladies hose, and which is formed of two blanked metal plates which are then bent to shape and afterwards welded alon their edges to form steam-tight joints. becured to the lower end of the form a is a tube 6 having a flange 0 near the lower end thereof. This flange may be secured to the tube in any desired manner and is seated on an internal flange d in a tube 6 extending upwardly from a pipe Surrounding the tube 1) above. the flanges c and d is a gland 9 having a screw-threaded engagement with the interior ofthe upper end of tube 6. Interposed between flange 0 and the lower end of the gland g is a metal washer: h and steam packing rings i. The packing rings are compressed between the washer ii and gland g, to form steamtight joints between the packing and tubes 7) and e, and at the same time permit tube 3) to be turned in tube 6. The weight of form a is supported on flange 01, while flange o is adapted to rotate between flange d and washer h, the latter of which will revent the cutting of the packing i by the ange a when the form is turned, and will reduce friction between the parts. The tube b. is journaledin the bore of gland g and flange (1. j is a stop connected to the upper end of tube 6 and is formed onone member of a split clamp is. The upper end of stop j extends into the plane of the form a and is arranged to prevent the form being rotated. in either direction beyond predetermined limits, and thereby prevent the forms from fouling with other forms adjacent thereto.

Located within pipe I is a second pipe Z having an upwardly extending nipple m concentric with. tubes 1) and e, and which telescopically engages the lower end of a tube 71. The tube nextcnds upwardly into the interior of the form (I, and preferably to the upper end thereof as indicated in Fig. 1, and is open at both endsto permitthe passage of steam theret-hrough, as hereinafter described; Thistube is preferably. fixedly secured to. the form a. and preferably. extends upwardly through the central portion thereof, and forms a spacer or support for preventing the indentation of the formforming sheets.

In the drawings, I have merely shown one form a supported from the pipe f. but in practice there are a series of such forms supported from the pipe. Each form is connected to pipes f and l in the manner shown,

and pipes and l are provided with valves for controlling the admission of steam to pipe Z and outlet of water condensation or steam and water from pipe In operation, the sLe-am passes from pipe 15, through pipe a, downwardly through the form a on both sides of pipe n to the pipe 7, through tubes 1) and c.

In the device shown in Fig. 2, the form is provided with the usual partition member and support 12. Where the device is provided with a partition member such as it is only necessary to extend pipe u a short distance upwardly in the form on one side of thepartition. In this form the steam passes up one side of the partition and down the other, but in both forms the steam delivery pipes are surrounded by the outgoing wet steam so that no portion of the outer surface of the inlet conduits for the steam is in contact with the atmosphere, but are surrounded by the outgoing steam. This prevents the condensation of steam in the inlet conduits, as the inner and outer walls are directly in contact with the steam and also provides means for conducting all the water of condensation from the forms to the outlet pipe or conduit.

In the form shown, the flange c is fixedly brazed or welded to tube 6 so that it nccessary to assemble the parts on tube i) before welding the flange to the tube Z) or welding the tube 5 to form a.

If desired, the flange may be removably secured to the tube as indicated in Fig. 5 in, which the flange c is provided with an in ternally threaded extension member into which is threaded the end of tube The flange may be secured against rotation by a through pin or a screw 0 as shown.

In this case, the outer surface of the ere tension of the flange is turned to rotatewithin the supporting flange in tube lhe advantages of my invention result from the provision of an internally heated form, which is adapted to turn on its support.

Further advantages result from the provision of such a form in which the steam is conducted to the interior of the form through. an inlet tube, and which is so arranged that all water of condensation from the form will pass to an outlet conduit. and thereby prevent water of condensation passing from the forms to the steam inlet pipe.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

l. A hollow drying form having concentric inlet and outlet tubes connected thereto, concentric inlet and outlet conduits telescopically connected to the inlet and outlet tubes, a flanged connection between the outer tube and the outer conduit arranged to permit free rotation of the tubes with relation to the conduits but to prevent axial movement of the tubes relative to the conduits, and a stufiing box in said connection to form a steam-tight joint between the outer tube and the outer cqnduit.

2. A hollow metal drying form having a tube connected to the lower end thereof, a conduit, a tube extending from the conduit, there being a steamlight swivel joint connecting said tubes to each other a second tube supported from the form within the first tube on the form, a conduit within the first conduit, and a nipple connected to the second conduit having a telescopic connection with the second tube supported from the form.

3. A hollow metal drying; form having a tube connected to the lower end thereof, a conduit, a tube extending from the conduit, there being a steam-tight swivel joint eon necting said tubes to each other. a second tube sumiorted from the form within the first tube on the form, a conduit within the I first conduit, a nipple connected to the second conduit having a telescopic connection with the second tube supported from the form, and a stop for the form arranged to prevent said form being turned more than 360.

4. A drying system comprising a steam inlet conduit, a return conduit, one conduit being within the other conduit, a nipple extending from each conduit the one nipple being within and concentric with the other nipple. a hollow drying form havingi two concentric tubes extending therefrom and telescopically engraging the nipples, and a flanged steam-tight joint between the outer nipple and the outer tube arranged to permit the form to be turned freely about the axes of the tubes and nipples but to prevent axial movement of the nipples and tubes.

In testimony of which invention, I have hereunto set my hand. at Philada, Penna. on this 10th day of July, 1922.
